Sure it does.

regression=# create table t1 (f1 int primary key);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "t1_pkey" for table "t1"
CREATE TABLE
regression=# create table t2 (f1 int references t1, f2 int);
CREATE TABLE
regression=# copy t2(f1,f2) from stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>> 3 4
>> \.
ERROR: insert or update on table "t2" violates foreign key constraint "$1"
DETAIL: Key (f1)=(3) is not present in table "t1".
